In the PV power station monitoring system solution, AOPRE-LINK8248 and AOPRE-LINK8480 are used to realize link redundancy uploaded to the station control layer through data acquisition, network transmission, central monitoring and port aggregation. The core computer room is composed of opal Internet Industrial Ethernet switch AOPRE-LINK8248, which gathers multiple ring network data traffic. The AOPRE-LINK8480 Industrial Ethernet switch forms a plurality of Gigabit redundant ring networks to form a redundancy protocol. Each ring network is physically isolated to improve the security of the network and ensure the worry free switching of the network.
